A£ROSCt TO OlTEft Figure 3.2 Air flow through impactor well and filter holder Figure 3.3 Example of a very sharp cut cyclone NOTE: Method designations, which certify that a particular FRM/FEM sampler or analyzer has been formally approved by EPA, are partially based on the type of size-selective 2.12-PM25 Reference/Class I Equivalent Methods The Federal Reference Method (FRM) for Particulate Matter (PM) developed by EPA's National Exposure Research Laboratory (NERL) forms the backbone of the EPA's national monitoring strategy. The United States Environmental Protection Agency (EPA) has a rigorous testing and certification process for regulatory monitors, with two designations: Federal Reference Method (FRM) and Federal Equivalent Method (FEM). EPA Contract No. 6. •Do the stated procedures meet method requirements? 2.5 FRM/FEM Performance Evaluation National Ambient Air Monitoring Conference Atlanta, GA - August 13, 2014 •Minnesota’s PM 2.5 Monitoring Network •Performance Evaluation Methods and Metrics •Results –Historic FRM/BAM relationship –Current FRM/FEM relationship •Lessons Learned Topics Covered. To reduce the biases between the FEM monitors and FRM samplers, empirical equations based on PM 2.5 concentrations (μg m −3), temperature (o C), and relative humidity (%) were derived to convert the FEM data to the FRM data. These reports are intended to assist monitoring agencies in understanding if the PM10 continuous monitors operated in their network are appropriate for their intended monitoring objective (i.e., comparison to the NAAQS and/or reporting the … In addition, a collocation guide has been developed to learn more about the collocation process. The E-FRM-DC has evolved from the previous E-FRM model, now making it more versatile, with greater applications from permanent long-term sampling at a fixed site or as an audit sampler for frequent relocation in remote areas. 2 FRM refers to Federal Reference Method, and FEM refers to Federal Equivalent Method. Since a number of the FEM monitors are (and will be) located in areas where FRM monitors used to measure PM 2.5 currently exist, a standard protocol for correlating PM 2.5 measurements from FEM monitors with PM 2.5 measurements from FRM monitors (used to make determinations of NAAQS compliance) must be developed to allow health researchers to measure/report ambient PM 2.5 … Meteorology (weather/transport patterns); 4. Purpose: These are Preliminary Comments from Members of the CASAC Air Monitoring and Methods Subcommittee (AMMS), related to the AMMS‘s review of EPA’s Ozone National Ambient Air Quality Standard (NAAQS) documentation that focuses on the EPA … Both FRM and FEM are the standard methods for PM 2.5 measurements and can be used interchangeably for state and local air monitoring stations (SLAMS) purposes (U.S. EPA, 2016). Prepared for U.S. Environmental Protection Agency, Research Triangle Park, NC. Regular calibration and audits of the measurement systems are performed to verify that the instruments are operating correctly, and data being collected is accurate. The sample screening level is a level of pollution in the air that is below what we expect to cause health problems from short-term exposures – all day, every day over a period ranging up to at least a couple of weeks (longer, for some pollutants). White Paper on the Approach for the Development of a New Federal Reference Method (FRM) for Pb in Total Suspended Particulates (TSP) On November 12, 2008 EPA substantially strengthened the National Ambient Air Quality Standards (NAAQS) for lead (see 73 FR 66934).
